Chrysler Repair: 05 pacifica, cv joints, cotter pin

Question
while accelerating the front end is making a sound.  the sound goes a little like this:  hmmmm hmmmmm hmmmm.

I took the vehicle and had all the tires balanced.  that reduced the noise.  however the vehicle has a pull on its left side and it is make another noise when I turn to the left or right.  I have been told that that noise indicates the cv joints will need to be replaced.  ok.  But I can not figure out what the hmmm hmmm hmmm sound is.  I am certain it needs an alignment.  The cv joints need to be replaced.  Could the other hmmm hmm come from the transmission or engine.  It doesn't even have 40,000 miles on it.

Answer
this might be possible

SUBJECT:
Front Hub/Half Shaft Click/Pop Sound
OVERVIEW:
This bulletin involves installing a rubber gasket to the face of the half shaft that mounts to
the hub bearing.
MODELS:
2004 - **2006** (CS) Pacifica
NOTE: **Every time the front half shafts are serviced, the rubber gasket must be
replaced.**
SYMPTOM/CONDITION:
Vehicle may exhibit a popping/clicking/snapping/ticking sound from the front hub/half shaft
area during acceleration after Drive to Reverse or Reverse to Driving shifts. The sound
may also be present while turning and accelerating from a stop.
DIAGNOSIS:
In order to determine if the popping/clicking/snapping/ticking sound is coming from the
front hub/half shaft interface, perform the following procedure:
1. Remove the cotter pin, nut lock, and wave washer from the end of both front half
shafts.
2. With the vehicle's brakes applied to keep the hub from turning, loosen both half shaft
nuts to zero torque.
3. With the service brake applied, shift the vehicle from Drive to Reverse and Reverse to
Drive. Once the transmission is engaged in gear, raise the engine speed to 1800 rpm.
4. If the sound is not present, perform the Repair Procedure. If the sound is still present,
**DO NOT replace the half shafts or hub bearings,** the source of the sound is
elsewhere. Further diagnosis is required.
